This portfolio showcased my early work (which was primarily video games) and gave me the opportunity to try out many fledgling web technologies. Among other things, it made use of responsive design, animations, and the speech recognition. This portfolio was designed to feel more like you were asking me questions than that you were navigating a website.
Feed the Forest was designed from scratch to work just as well on phones as on full-sized computers or tablets. It uses CSS media queries to adapt to the width of the display.
There are a combination of various animation techniques at work in this portfolio. When you first load the site, you may notice that one or more trees grow. These are procedurally generated, so they're different each time. At night time the background of the page will have stars and dark colors, whereas it's a bright blue during the day.
But the background isn't just a still life after that! While you're navigating the site it may rain or snow, or flocks of birds my fly past (only if it's time for them to migrate, of course). All of these effects are done using HTML5 canvas.
There are also plenty of CSS3 transitions in use. These help keep elements from just appearing or disappearing without explanation.
This portfolio actually supported both Speech Recognition and Speech Synthesis. In other words, you could speak to the portfolio out loud, and it would speak back to you, also out loud. You can try it out for yourself by visiting the site and clicking the microphone icon on the main text box, if you're in Google Chrome.
Both of these features are supported by JavaScript APIs that were brand new at the time, and which (as I'm writing this) still aren't supported in many browsers.
